引入向前、向左两个偏向强度D1、D2来确定单向通道中行人向各方向运动的几率,应用元胞自动机模型对在不同偏向强度下行人的疏散过程进行模拟.结果表明,疏散时间随着向前偏向强度的D1增大而减少;D2对疏散时间的影响随着通道宽度和D1的不同而不同.
Introducing the strength of the drift D1 pointing to the exit and the strength of the drift D2 pointing to the left to determine the walker' s transition probabilities in a corridor, this paper discusses the application of cellular automata model simulates the pedestrian' s evacuation process under the different strength of drift. The results show that evacuation time becomes less with the increase of the D1 ; under the different of the width and D1 ,the evacuation time differs with the D2.
